During a walk-through of SKIMS' 'Naked' collection, Kim Kardashian West called out this low, plunging bra as her favorite from the line. It's made from soft, second-skin fabric that's remarkably thin - the founder says it just molds to you and stays. It has no underwire (so it's even comfortable enough to sleep in) and color-matched hardware at the adjustable shoulder straps. Our edit includes all four shade options.
